FLEXIBLE STANDARD AND CONDUCTOR FOR ELECTRIC LIGHTS.

SPECIFICATION forming part of Letters Patent No. 375,702, dated December 27, 1887.

Application filed April 4, 1885. Serial No. 161,192. (No model.)

To aZZ whom it may concern.-

Be it known that I, ERNEST G. FASOLDT, of the city and county of Albany, in the State of New York, have invented a new and useful Flexible Standard and Conductor for Electric Lights, of which the following is a specification.

The object of my invention is to provide a flexible standard or holder for electric lights, which shall be composed of lines of conduct ing-wires insulated from each other and so arranged that the standard may be bent over into any required position and restored to its normal condition without breaking the contiunity of the electrical circuits. This object I attain by means of the construction illustrated in the accompanying drawings, which, being herein referred to, form part of this specification, and in which- Figure 1 is a partial frontelcvation and vertieal section of my flexible holder fitted to a metallic base-plate; Fig. 2, a longitudinal sec-v tion of my flexible holder attached to a handle; and Figs. 3 and 4t are respectively enlarged front and side elevations of the upper part of my flexible holder.

As represented in the ,drawings my flexible holder is composed of a soft-wire core, A, which is covered by a coating, B, of insulating material, and the latter is surrounded by an outer covering, 0, of conductingwire, which may be wound spirally, as shown in the drawings, so as to form an outside covering of proper electrical conductivity and possessing sufficient flexibility to allow it to be bent quite abruptly into any form that occasion may require. The core-wire A, I preferably make of soft copper or other pliable material that will bend freely without danger of breaking and that possesses the proper degree of electrical conductivity. At the upper end of the holder a metallic bracket, D, is joined to the outer covering, 0, so as to preserve the continuity of electrical conductivity, and said bracket is adapted to hold an incandescent electric lamp, E,and arm (1 of said bracket is electrically connected to one of the conductingwires e, which runs up into the lamp E, where it connects with one end of the filament a The opposite conducting-wire, c, is electricallyconnected to the corewire A of the holder, and thereby the means for conducting an electrical current through the filament e" is properly established.

As shown in Fig. 1, my holder is fixed to a metallic base-plate, F, to which the base of the outer covering, 0, is electrically connected. A binding-post, f, electrically attached to the base-plate F, affords the means for connecting one of the battery-wires G. The insulated core-wire A is connected beneath the baseplate with the binding-post f, whose lower part passes through a sleeve, f, of hard rubber or other suitable non-conducting material, whereby the bindingpostf will be perfectly insulated from the base-plate F. The wire Gconnectsthe binding-postfto the opposite side of the battery and completes the electrical circuit.

Vhen constructed as above described, my apparatus is particularly designed for use with microscopical investigations, and when so used the holder may be bent over, as indicated by dotted lines in Fig. 1, so as to bring the lamp E beneath the center of the stage of the microscope in such position that the rays of light will pass directly through as they do when rays of reflected light are employed.

As shown in Fig. 2, my flexible holder is secured to a handle, F, of hard rubber, wood, or other material that is a non-conductor of electricity. \Vhen made in this form, the outer covering, 0, is connected to a conducting-wire, c,which passes longitudinally through the handle F and connects electrically with the binding-postfat the base of the handle. The core 85 wire A is connected by the conducting-wire c to the binding-postf, which is also fixed in the base of the handle.

XVhen made as last described, my apparatus is particularly designed for use in surgical explorations, and with the parts properly proportioned the flexibility of the holder permits it to be bent into such form that the lamp E can be readily introduced into the throat, the

rectum, or any artificial incision, so as to afivity, the said eorewire, outer covering, and ford abundant light forinternal examinations. bracket being electrical conductors, and the i0 Iclaim as my inventionsaid core-wire being electricallyinsulated from The combination, in a flexible holder for the outer casing, as herein specified. 5 electric lights, of a pliable core-wire, A, an ERNEST O.
